I have not read them all either but a great bunch of them... My first one was Mort and I will never forget to imagine Death drinking liquors LOL, It's really sad he had such an early onset of Alzheimer considering his wits, and despite his many donations for research he could not avoid what I believe he may have feared the most... but his humour and creations will surely remain for all of us to enjoy for many generations. I'm pretty sure (if not yet) he will always mentioned as a fantasy author classic just like Tolkien or Ende.
